rMPPLOVEMENT IN BUTTONS.

Specification forming part of Letters Patent No. 40.254, dated October 13, 1.863.

.To'aZZ whom it may concern,.- A

Be it known that we, ACHILLE AUGUSTE FELD'IRAPPE and REN-DUTFOY, of Paris, in the Empire of France, have invented anew and Improved Button; and we do hereby declare that the following is a full, clear, and

exact description of the saine, referenceL being had to the accompanying drawings, forming part of this specification, in which- Figure-1 is a back view of the button. Fig.

l2 is a central section of the same in the plane -indicated by the liuc .v .v in Fig. l.

Fig. 3 is aside view ofthe saine at right angles to Fig.' 2.

Similar letters of reference-indicate corresponding partsin the several figures.

This invention consists in a button without cither'a projecting shank or any hole through its face, but having its attachment to a garment provided for by means of a hole or tunnel passing transversei y through the body.

This button maybe made of porcelain or other ceramic material, or of any substance which is sufficiently plastic undercertain conditions to enable it to be molded in molds, or formed by pressure in dies to4 the desired shape, and may be manufactured in one piece by any molding'or pressing machinery or apparatns adapted to the manufacture of such 1t may be of various forms externally, but we prefer to make its back of spheroidal form, as that form is 'bestadapted to the proper arrangement of ,the hole Yor tunnel anwhich extends. transversely and centrally through it. At each end of the hole or tunnel 'a there is formed in the back a cavity, '11, of a width and depth greater than the such cavities being to facilitate the passage ot' the needle through the hole a, and to form in rear ofthe said hole a narrow shank, c, for

the attaching-thread to pass around. This shank, however, it will be observed, does not project beyond the back of the body ot' the button, which is vthus allowed to lie closer against the garment than an ordinary shankbutton, while it presents a neater appearance y than a button whose face isperforatcd.-

To attach the button, the threaded needle is passed through the cloth or other material and through thehole a alternately, in the saine manner asin sewing on a shank-button.A

l'hongh we prefer generally to make the button all in one piece, it may be practicable, and even desirable for some purposes, to make the hole aA and shank o wholly or partly ot' a separate piece of similar material to the rest of the button, and unite saidpiece with the body by fusion in the baking process, or by other means, according to the nature of the substance of which the button is composed.

We do not clninranaking a button with a bar formed in its back as a substitute for a sha-nk; but a What we claim as our invention, and desire to secure by Letters Patent, is-

A button of porcelain or other material, without either a projecting shank or any hole in its face, but havin g a hole or tunnel extending transversely through the back part -of its body, substantially as herein specified.
